From c2735391fbc68feae10d6d14e60956c8106e725f Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sat, 10 Sep 2011 12:26:07 +0200 Subject: [PATCH] arm: mx28: fix bit operation in clock setting reg | (1 << clk->enable_shift) always evaluates to true. Switch it to & which makes much more sense. Same fix as 13be9f00 (ARM i.MX28: fix bit operation) at a different location.
